Biosurfactants have garnered increased attention lately due to their superiority of properties over fossil-derived counterparts. While the cost production remains a significant hurdle surpass synthetic surfactants, biosurfactants been anticipated gain larger market share in coming decades. Among these, glycolipids, type low-molecular-weight biosurfactant, stand out for efficacy reducing surface and interfacial tension, which made them highly sought-after various surfactant-related applications. Glycolipids are composed hydrophilic carbohydrate moieties linked hydrophobic fatty acid chains through ester bonds that mainly include rhamnolipids, trehalose lipids, sophorolipids, mannosylerythritol lipids. This review highlights current landscape glycolipids covers specific glycolipid productivity diverse range products found global market. Applications such as bioremediation, food processing, petroleum refining, biomedical uses, increasing agriculture output discussed. Additionally, latest advancements reduction challenges utilizing second-generation feedstocks sustainable also thoroughly examined. Overall, this proposes balance between environmental advantages, economic viability, societal benefits optimized integration secondary biosurfactant production.

Low-molecular-weight (LMW) molecules of biological origin like microbial glycolipid biosurfactants can self-assemble in water, with a tunable structure by soft chemistry approach (pH, temperature, and ionic strength). The unique molecular glycolipids gives possible access to wide variety aqueous self-assembled structures, although highly unpredictable beforehand. presented here consists glucose group linked C18:1-cis fatty acid (G-C18:1) produced the fermentation Starmerella bombicola ΔugtB1. Due carboxylic acid, supramolecular self-assembly is pH dependent. In range 5–7, G-C18:1 forms vesicles, while above 7, it micellar phase. Adding metal salts (ion radius ascending order: Al3+, Fe3+, Ni2+, Mg2+, Cu2+, Zn2+, Co2+, Fe2+, Cr2+, Mn2+, Au3+, Ca2+, Ag+, Sr2+, Ba2+), vesicle phase generally precipitates. Metal complex speciation (Al3+, Fe2+) added drive formation wormlike gels, often observed for surfactants water. On contrary, free ions (Cr2+, Ag+) same unexpectedly hydrogels fibrillar structure, amphiphiles (peptides, peptide-derivatives) but not surfactants. Oscillatory rheology shows that elastic properties vary between few tens Pa up 5 kPa given glucolipid concentration (3 wt %). This work hence first example preparing metallogels from

Biosurfactants are amphiphilic molecules capable of reducing the surface tension water and forming emulsions between immiscible liquids. These versatile find applications in different industrial sectors, standing out environmental applications, such as bioremediation agents contaminated environments. Bioremediation is an emerging sustainable method controlling degradation waste. The present study carried a bibliometric analysis, reviewing all research published SCOPUS database up to 2023, focused on producing biosurfactants from sunflowers with this waste degradation. Using produce proved ecological, sustainable, economical alternative conventional substrates. results showed that only seed husks, oil derived seed, sunflower stems were used biosurfactants, emphasizing most raw material, probably due its rich linoleic acid content. preliminary selection detected 12 articles addressed subject under analysis. According these studies, tested high potential for application processes able decontaminate soil, water, liquid effluents. analysis was performed VOSviewer software evaluate quality publications and, above all, show more comprehensive scenario based following indicators: productive journals, by country, cited articles, recurrent keywords, institutions. insights will undoubtedly help scientists develop new practices contribute using sunflowers. By showcasing benefits practicality sunflower-derived contributes broader discourse bioremediation, fostering innovative eco-friendly management solutions.

Biosurfactants have emerged as promising agents for environmental remediation due to their ability complex, chelate, and remove heavy metals from contaminated environments. This review evaluates potential recovering critical minerals waste materials support renewable energy production, emphasizing the role of biosurfactant–metal interactions in advancing green recovery technologies enhancing resource circularity. Among biosurfactants, rhamnolipids demonstrate a high affinity such lead, cadmium, copper strong stability constants functional groups like carboxylates, with efficiencies exceeding 75% under optimized conditions. Analytical techniques, including Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Fourier-Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM), are instrumental assessing efficiency interaction mechanisms. The introduces Green Chemistry Metrics Framework evaluating biosurfactant-based processes, revealing 70–85% lower Environmental Factors compared conventional methods. Significant research gaps exist applying biosurfactants extraction lithium cobalt batteries other materials. Advancing hold promise efficient, sustainable metal circularity, addressing both scarcity protection challenges simultaneously.

Abstract Mannosylerythritol lipids (MELs), a glycolipid biosurfactant, possess great potential in many high‐value‐added fields. However, its water‐insolubility is an important obstacle to wide application, especially home and personal care In this study, new strategy “killing two birds with one stone” based on the chemical modification of natural MELs was developed for preparation hydrophilic MELs. These newly prepared can be efficiently isolated from reacted solution via stepwise extraction methanol/ n ‐hexane system. 88% were recovered MELs, corresponding yield 50%. This mainly attributed esterification fatty acids, representing main relatively‐difficult‐to‐remove impurities fermentative‐produced facilitating separation MEL product extraction. Moreover, these presented comparable surface activities while exhibiting enhanced water solubility biocompatibility. originates generation MEL‐D, resulting deacetylation formation containing just hydrophobic chain (named “MEL‐G”). Hence, present not only beneficial removal (fatty acids) but also improved hydrophilicity.
